CAR-TRUCK.

.To all whom it may concern:

Be it known that I, ETHAN I. DoDDs, a citii zen of the United'States,residing at Pullman,

owingis a specification.

This invention relates to car-trucks of the pedestal type, and is moreespecially directed to vthe construction of the side frame and to thetransoms and means and manner of fastening them in place.

l plus material.

In order` to save weight and metal in the 'side frame and at the sametime produce a structure of great strength, I have devised the onearticularly described below and illustrated) in the accompanyingdrawings, which is chiefly characterized by a main plate or webortionwith integral ribs or anges exten ing from both sides. These ribs orfianges are so disposed as to properly take the strains without the useof any sur- I also provide the lower pedestal portions with okes unitedby bolts, which prevent the axles from leaving the side ame in case thecar becomes overturned and which also shield the main portion of theframe from blows or shocks due to accidents or otherwise. If theseprotecting yokes or clips and their bolts become damaged, they can bereadily and cheaply replaced.

Referring to the accompanying drawings, wherein I have shown a carembodying my invention, Figure 1 illustrates a side eleva tion of myimproved truck. Fig. 2 represents a plan view'thereof, and Fig. 3 showsa section on the line 3 3 of Fig. 1.

The main plate ortion or web of the side frame is provi ed at its upperedge with compression ribs or flanges 11, extending in olppositedirections from the main web, as c early shown in Fig. 3. At the loweredge of the main web 10 I provide a tension rib or flange 12, similar tothe compression-flange 1 1 above, and connecting the two flanges arevertical ribs 13 on each side of the plate or web 10. On both sides ofthe main web, ex-

tending from the lower portion of the outer vertica ribs 13 to the partsof the side frame over the journal-boxes, are inclined tensionribs 14,15, and 16, also on both sides of the main web. The ortion of the frameover the ournal-boxes is su plied with a rib 17 in addition to the rib11, a ready described, said Specification of Letters Patent.

rib bein virtually an extension of rib 15, both of t e ribs 11 and 17 atthe end of the frame turning downward, as is illustrated in Fig. 1.intervals by vertical ribs 18, which also connect them to the combinedcap land edestal 22, formed with downwardly-extending' side flanges 22,as is illustrated in 3. Be-

These two ribs are joined together at tween the journal-boxes 20 and thecombined caps and pedestals 22 I insert the usual springs 21. Thedepending end portions 19 of the side frame are supplied at their lowerends with yokes 24, secured in place by bolts; 26, and connecting theseyokes with similar ones on the adjacent portions of the central part ofthe side frame are bolts 25. These yokes and bolts act not only asdevices for shielding the truck from blows and other injuries, but alsoconstitute means for binding the end portions of the sideframe tothe-main central portion, thus strenglhening the structure. The bolts 26ass t the frame, as is illustrated in Figs. 1 and 3. `1

By these recesses I save somewhat in weight and material, at the sametime retaining a strong construction.

The transom comprises two channel-beams 27, which are secured to themain web of the side frames by means of angle-plat'esf-ZS. Riveted tothe upper flanges of the transomchannels and to the upper flanges of theside frame is a plate 29 of the shape illustrated in Fig. 2. A similarplate 30 is secured to the lower flanges of the saine parts.

It is clear that a car-truck such as that above described has nosuperfiuous metal, but that by the proper disposition of the anges andribs I secure a light strong structure abundantly reinforce against allthe strains to which it is subject 1n use. It is also apparent that theside frame can be readily separated lfrom the transoms, if desi red.

Obviously various modifications may be made in such a constructionwithout departing from the essence of my invention.

IOO

This patent is intended to embrace only so I much of the disclosure madeherein as is covered by the claims.

I claim- I 1. A side frame for a pedestal-truck havand a plura ity ofintegral ribs extend- $75 ough recesses 23 Y. in the interior part o thepedestal portions of ing from the lower part of said plate portion overeach pedestal, substantially as described.

2. A side frame for a pedestal-truck havin a main plate portion betweenthe pedesta s, and a plurality of integral ribs on each side of saidplate portion extending from the lower part thereof over each pedestal,substantially as described. 'i

3. A side frame for a pedestal-truck having a main plate portion betweenthe pedestals, a plurality of integral ribs extending from the lowerpart ofsaid plate portion over additional integral ribs, substantiallyas described.

5. A side frame for a pedestal-truck, having. a main plate portionbetween the pedestals with an integral flange along its lower edge andan integral rib extending from said flange over each pedestal,substantially as described.

'6. A side frame for a pedestal-truck having a main plate portionbetween the pedestals with an integral flange along its lower edge, anda plurality of integral ribs extending from said flange over eachpedestal, said ribs being connected together by one or more additionalintegral ribs, substantially as described.

7. A side frame for a pedestal-truck having a main plate portion betweenthe pedestals with an integral flange along its lower edge, an integralrib extending from said flangeA over each pedestal, said plateportionhaving an integral top flange conneetingsaid n ribs, substantially asdescribed. 45

8. A side frame for a pedestal-truck having a main plate portion betweenthe pedestals with integral flanges along its lower and upper edges andvertical ribs joining said flanges, an integral rib extending from the5o ing a main plate portion between the pedes- 55 tals with integr topand bottom flanges, and vertical ribs joining said flanges, an integralrib extending from the junction of said bottom ange and adjacent endmostvertical rib over each pedestal, and an integral rib 6o connecting eachof said junctions with its adjacent spring-cap, substantially asdescribed.
